3 Claims.

The .inventionrelates toabsorbent pads for feminine hygiene.

Theprimary object of the. invention is to provide such a pad which gives improved comfort, cleanliness and sanitation to the wearer.

Another object of theeinvention is to provide a .pad which is .sov conformed to the feminine anatomy as to fit properly and to avoid pressure on adjacent muscle structures.

A further object of the invention is to provide a pad which will not rub contaminants from the rectum or adjacent parts of the body into the vagina.

Still another object of the invention is to provide a pad with a main body portion which is not distorted and compressed by the legs when worn.

An additional object of the invention is to provide a pad which securely seals against the escape of fluid, thus preventing contamination of clothing or other parts of the body and also allowing time for full absorption of the fluid into the pad.

Still a further object of the invention is to provide a pad which has more absorbent material at points where it is effective than those heretofore available, and which thus serves for substantially longer periods of use.

It is also an object of the invention to provide a pad which is very inconspicuous when worn.

Further objects and advantages of the invention will appear more fully from the following description, especially when taken in conjunction with the accompanying drawings which form a part thereof.

In the drawings:

Fig. 1 is a top plan view of a pad embodying my invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is a cross-section on the line 3-3 of Fig. 2;

Fig. 4 is an anatomical sketch showing the pad in use; and

Fig. 5 is an anatomical sketch showing the relation of the pad to the feminine anatomy.

The pad is composed of a main body portion 2 and a second portion 4. Portion 2 is of such length (for example, slightly over six inches) as to extend only from a point forwardly of the rectum 6 (see Figs. 4 and 5), that is a point between the frenulum 8 and the rectum, to a point opposite the anterior part I 0 of the vestibule. The main portion is narrower in the center as at l2 than at its ends [4, 32 (for example, slightly under two inches to slightly over two and a half (Cl. l28--290) inches) sothatthis central portion will remain substantially flat and will not buckle or bend downward between the legs;

This effect isimproved; by the fact that the main portion is formed of several parallel layers of absorbent material. For example, as shown in Fig. 3, there maybe fourlayers 15,1810 and 22. Layers I 6 and 22'may be formed of several strips of embossed 28-caliper absorbent paper; layer it of several similar strips, with an absorbent cotton filler therebetween; and layer 20 of several similar strips with such a filler, whipcord embossed.

The second part is formed of one or more layers 24 similar to layer [6 rolled or folded around each other to form a body of somewhat greater height than width. The forward end 26 is slantingly undercut as shown in Fig. 1. This part is substantially centrally positioned on the main body part, but is both shorter and narrower. For example, it may be around four and a half inches long, one inch wide and two inches high.

The two parts may be secured together by crimping the paper layers with each other at the meeting plane 28. The two are enclosed in a tube 36 of gauze which extends beyond the ends of the pad for connection to a belt or supporter to hold the pad in position on the wearer. The front end 32 of the main body portion is folded up against slanting face 26, as shown in Fig. 1.

As is shown in Fig. 5, the pad, when properly positioned on the wearer, extends from about the front of the labia minora to the frenulum pudendum. The part 24 is of about the length of the vaginal orifice.

Fig. 4 shows the effect of such a pad. The rear edge of the small portion will engage the frenulum as at 34, thus providing a damming action which retard leakage of fluid towards the rear. The rear edge of the main body portion will also engage the body at a point 36 forward of the rectum, giving a second damming action and preventing the escape of fluids to the rectal area as well as from such area to the genital organs.

The front edge of the pad engages the anterior portion of the vestibule, as at 38, and thus prevents the escape of fluids towards the front. The smaller pad portion fits at least partially between the labia and absorbs the fluids at their point of emission.

Such a pad creates no pressure on the rectum, and therefore is more comfortable than most pads presently available. It avoids contamination or soiling of other parts of the body and of the clothing by the menstrual fluids, as well a contamination of the genital organs from the rectum. The posterior portion engages the frenulum and extends into the vaginal opening. The anterior portion is flattened and spreads out over the clitoris and adjacent parts so that the pressure is distributed and does not cause discomfort.

The damming action previously described holds the fluids in contact with the pad long enough for them to be properly absorbed therein. Thus escape of the fluids is prevented, and the pad can be worn for a longer time. Also, because of its shortness, it is not discernible when worn.

While I have described herein one embodiment of my invention, I wish it to be understood that I do not intend to limit myself thereby except within the scope of the claims hereto or hereinafter appended.

I claim:

1. An absorbent pad for feminine hygiene, comprising a main body member of absorbent material of a length to extend only from a point between the rectum and the frenulum to the anterior part of the vestibule, and a second member of absorbent material secured on one face of said main member and being narrower and shorter than said first member and being so located on the first member and of such dimen- 4 sions as to fit between the labia against the vaginal orifice, said first member being wider at its ends than at its center and said second member having a slantingly undercut front end.

2. A pad as claimed in claim 1 in which the main member is formed of layers of absorbent material, all the layers being substantially parallel to one another, and the second member being secured to the first member.

3. An absorbent pad for feminine hygiene, comprising a main body member of absorbent material of a length to extend only from a point between the rectum and the frenulum to the anterior part of the vestibule, and a second member of absorbent material secured on one face of said main member and being narrower and shorter than said first member and being so located on the first member and or such dimensions as to fit between the labia against the vaginal orifice, said second member having a slantingly undercut front end.
